Whoever gets the greatest number of donations to their grassroots fundraising page between now and 11:59 p.m. this Saturday night will win a call from President Obama—for themselves or anyone they choose.

And we're adding a twist this time around: Another winner will be selected from a pool of everyone who gets 10 or more contributions.

This Saturday is a huge fundraising deadline, and the donations you bring in through your grassroots fundraising page will play a major part in helping us meet our goal.

That's why I love grassroots fundraising. When your friends donate to your page, they're stepping up to own a piece of this thing. You might even end up inspiring a few of them to create their own pages—and start getting their own networks involved in re-electing the President.

So let's go. You've got six days to win a phone call from the President—start thinking about what you'd ask him, or who you'd want him to call.

No purchase, payment, or contribution necessary to enter. Contributing will not improve chances of winning. Void where prohibited. Entries must be received by 3/31/12. You may enter by creating a Grassroots Fundraising Page here. One winner who raises contributions from the greatest number of contributors, and a second winner selected from all entrants who raise contributions from at least 10 unique contributors (both during the Promotion Period) will each will receive a call from Barack Obama. Promotion open only to U.S. citizens, or lawful permanent U.S. residents who are legal residents of the 50 United States, District of Columbia and Puerto Rico and 18 or older (or of majority under applicable law). Promotion subject to Official Rules and additional restrictions on eligibility. Sponsor: Obama for America, 130 E. Randolph St., Chicago, IL 60601.
